Tentakel - distributed command execution
Tentakel is a program for executing the same command on many hosts in parallel using ssh.
Tentakel has the following features:
- Parallel execution of commands on several hosts.
- Format strings that control how the output of the remote commands is about to be displayed and how the output of different hosts should be separated from each other.
- A powerful configuration file that can be used to define groups of hosts. Such groups can contain other groups. Each group can be assigned a remote method, a username and a format string.
- Easy extensibility to allow for different remote methods (currently only ssh and rsh are supported).
It does not try to be a complex Distributed Resource Management System (DRM) like the Sun Grid Engine or Condor. Tentakel aims to be useful mainly for administration purposes.
